Checking in on passer ratings and QBR

Here’s a breakdown of AFC South quarterbacking on Sunday, with QBR (and rank for the day) as well as passer rating.

Passer rating maxes out at 158.3; QBR goes to 100. Here’s QBR for everyone this week.

For a game, QBR can be interpreted as a percentile, so a score of 80 means a QB’s performance was better than 80 percent of all QB games.

A reminder on Total QBR: It’s a quarterback rating that takes into account all of a QB’s significant contributions (passing, rushing, sacks, fumbles, penalties) to his team’s scoring and winning and summarizes them into one number on a 0-100 scale, where 50 is average. Since 2008, the team with the higher QBR has won 86 percent of the time.
